1.The potential value of microRNA in the development of tuberculosis and its early diagnosis
Chinese Journal of Laboratory Medicine 2014;(5):330-333
Tuberculosis a disease with the highest death rate by single pathogenic infection can cause serious harm to human health .MicroRNA ( miRNA ) is a classical single-stranded, short RNA molecules ( about 21 to 25 nucleotides ) that plays an important role in cell proliferation , differentiation , senescence and apoptosis by inhibiting the post-transcriptional gene expression or promoting degradation of target gene mRNA . Recent studies have shown that miRNA involved in the regulation of apoptosis , expression of pro-inflammatory cytokines , inflammation-related signaling pathways in tuberculosis infection . Meanwhile, miRNA may be a new biomarker for tuberculosis diagnosis.
2.AN IMMUNOLOGIC STUDY OF MIDGE DERMATITIS CAUSED BY FORCIPOMYIA (LASIOHELEA) TAIWAN (SHIRAKI, 1913)
Academic Journal of Second Military Medical University 1985;0(05):-
Before and after artificial immunotherapy (desensitization) for midge dermatitis, the authors determined immunologic status of some patients.It was found that their functions of cell-mediated immunity were lowered, manifesting as decreased number of Ts lymphocytes, raised circulating IgG level, decreased total hemolytic complement, and significantly increased immune complex positive rate.At the end of therapy, the number of Ts lymphocytes and total hemolytic complement rose. The authors consider that the lowered function of cell mediated immunity plays an important role in the pathogenesis of midge dermatitis.In addition to type Ⅰ and Ⅳ hypersensitivity, type Ⅲ hypersensitivity may also be present because of the increased immune complex positive rate.

China Pharmacy 2016;27(25):3461-3463
OBJECTIVE:To provide a reference for further strengthening the supervision and administration of the management and use of Papaver somniferum. METHODS:The general information,clinical application and toxic reactions of P. somniferum were briefly described by reference to relevant literatures and on the basis of the actual work. According to current laws and regula-tions,the existing problems about the clinical application and management of P. somniferum were revealed,and relevant counter-measures and suggestions were put forward. RESULTS&CONCLUSIONS:Both toxic and addictive,P. somniferum is the only tra-ditional Chinese herbal medicine covered by narcotic drug management. It is mainly used in clinical practice to relieve cough,diar-rhea and pain,etc. Although relevant laws and regulations have provided the specific requirements for the production,purchase, use and research & development of P. somniferum,slack enforcement of the laws and regulations,irrational use and abuse still ex-ist. It is suggested that State Food and Drug Administration and health administrative departments should constantly improve rele-vant law and regulation system and detailed regulations,strengthen supervision and administration,and strictly enforce relevant laws and regulations at the units engaged in the production,management and use of P. somniferum. Meanwhile,competent authori-ties should strengthen publicity and training.
5. Nano Letters: micro-electrochemical biosensor provides a new method for portable detection of disease biomarkers
Journal of Shanghai Jiaotong University(Medical Science) 2019;39(1):1-3
Molecular transport controls the efficiency of complex biological network systems such as cellular signaling system and cascade biomedical reaction. However, device fabrication for molecular sensing is often restricted by a low transport effciency and complicated processing. Here, we report a molecular threading dependent transport system using three-dimensional (3D) paper origami enabling the directional transport of biomolecules. We demonstrate that framework nucleic acid based interface engineering allows orthogonal molecular recognition and enzymatic reaction with programmed order on site. We thus develop a single-step electrochemical DNA sensor for quantitative analysis with 1 picomolar sensitivity within 60 min. Our sensor can discriminate a mismatched target at the level of a single base mismatch. Our study shows a great potential toward the development of a biomimetic molecular transport system for point-of-care and precision diagnosis.
